Of course, as I typically caution on Black Friday and Cyber Monday, don’t let FOMO get the best of you. Just because something is on sale doesn’t make it the best deal of all time. So make sure you know how to determine if that Prime Day deal is really a deal. Right now I’m a big fan of the CamelCamelCamel browser plug-in, because with one click I can see a product’s complete price history.

To that end, I’ve cut through all the Prime Day hype to bring you the deals I think are worth your time. And check back often: I’ll update this list throughout the day as new deals bubble up.

Last update: July 17, 2:35 p.m. PT.

Amazon-branded stuff

Amazon Fire TV Stick: $20. Amazon’s streaming stick has frequently been on sale for $30, but today it’s at an all-time low. Is it better than the equivalent Roku? Well, it’s certainly cheaper, and its Alexa-powered voice controls are, I would argue, better than what Roku currently delivers on the voice front.

FIRE TV STICK FOR $20Refurbished Echo 2nd-gen: $60. Wait a sec. If the Echo is priced at $70 new (which it is for Prime Day, down from the usual $100), why go refurb to save only $10? Simple: It’s literally good as new, with a full one-year warranty. So why not save $10 if you can save $10? Take note, however, that that price is good only for the cloth-covered versions; if you want a wood finish, there goes your $10 savings.

Speakers and audio

Dock your Dot in this robust portable speaker from Ninety7.

The Vaux portable speaker dock for Echo Dot: $30. Although some reviewers have encountered reliability issues, I’ve owned one of these for about eight months, and so far, so good. Great speaker upgrade for a second-gen Dot, great way to make it more mobile (thanks to its rechargeable battery). It normally runs $40. Update, July 17: This deal is now active, but it’s a Lightning Deal scheduled to end at 12:30 p.m. PT (unless it sells out first).

VAUX DOCK FOR $30The Aomais Life 30W portable Bluetooth speaker: $50 with code RX5JW3FR. Like bamboo? Check out the front of this bookshelf-style speaker, which features a stylish bamboo bezel, dual drivers and a passive subwoofer. And while it looks like something that’s meant to stay put, it can play for up to 10 hours on the go, according to Aomais. It normally sells for $80.

Mobile phones and accessories

This portable AC outlet is $45 off for Prime Day.ChargeTech

The ChargeTech Portable AC Outlet Battery Pack: $140 with code AMUZISNW. Powerful enough to charge not only your phones and tablets but also your laptop, this 27,000-mAh power bank features a three-prong AC outlet that supports a maximum draw of 85 watts. It often sells for as much as $225 and hasn’t dipped below $185 since 2017.

AC POWER BANK FOR $140The Moto X4: $200. Now this is a Prime Day deal. The fourth-generation Moto X (aka Moto X4) phone has been selling for $299 from Motorola proper, but Amazon has scarcely dipped below $279 since adding it as a Prime Exclusive phone earlier this year. At $200, it’s definitely an all-time low — and a killer buy, as evidenced by CNET’s overwhelmingly positive Moto X4 review.

The Nokia 2 for $79. That’s your price at checkout; it’s normally $99. The Nokia 2 is an unlocked GSM phone with a 5-inch screen, big battery (4,100mAh!) and room for two SIM cards (or one SIM and a microSD card — the latter probably more important given the measly 8GB of internal storage). Granted, reviews are mixed, but a Nokia-branded Android phone for $80 is pretty amazing.

TVs and smart home

The Toshiba 50-inch 4K LED TV – Fire Edition: $290. This model, introduced earlier this year, has never sold below its $400 regular price. No need to add a Roku or even Fire TV — the Toshiba has the latter baked right in. You also get an Alexa-friendly remote with shortcut buttons to streaming services like Netflix, HBO and — natch — Amazon Video.

The Sensibo Sky smart air-conditioning controller: $99. If you own one of those wall-mount AC units, you can make it smart and save a hefty $50: The Sensibo Sky is normally $149. Just mount it underneath so it can point at the AC’s IR receiver. From there you can use your phone to do all the usual “smart” things: set schedules, control it from afar and so on. It works with voice controls, too.

Smartwatches and fitness trackers

The Fitbit Alta HR: $90. The new Fitbit Versa appeared on our list of embargoed Prime Day deals, but Fitbit tells us no such bargain is planned. However, the Fitbit Alta HR — one of CNET’s favorite fitness bands of 2017 — is definitely 40 percent off. Update, July 17: As of this morning, only two Alta models remain: black and blue-gray, both in small.

ALTA HR FOR $90Me, I’m still of the opinion that the best smartwatch/fitness-tracker deal is the Amazfit Bip (currently $70 at Amazon, down from $100 — though not specifically as a Prime Day deal). It’s not perfect, but, wow, it’s way cheaper.

Laptops, PCs, Chromebooks and tablets

AcerThe Acer Chromebook 11: $140. Just your basic 11.6-inch Chromebook, one with 4GB of RAM and 16GB of storage. But Amazon has never sold it for less than $190, so this is definitely a good savings — and probably a great first computer for a young student.

The best of the rest

The MegaWheels hoverboard: $116 with code ANXTFLB2. So help me, I still think hoverboards are cool — even if they don’t actually hover. Instead, they scoot around on two wheels, and provided you’re safe about it, they’re lots of fun. This code works only with the black model, which has solid reviews and a 12-month warranty.

MEGAWHEELS SELF-BALANCING SCOOTER FOR $116The Tile Mate 4-pack: $29. That’s an extra $5 off (which you’ll see when you add it to your cart) an already good deal, because normally this bundle runs $50. The Tile Mate is a Bluetooth tracker that pairs with your phone and attaches to your keychain, TV remote, backpack and other often-misplaced items.

The Crock-Pot programmable 6-quart cooker: $50. The Instant Pot gets all the attention, but this eight-in-one cooker does all the same things — for a full $20 less, at least today. (The $50 final price appears at checkout.) This model was a bit cheaper last Black Friday, but still a great buy on a highly rated Instant Pot alternative.

CROCK-POT COOKER FOR $50The Tacklife Jigsaw: $39.48 with code W5NDTE68. Tool time! This 6.7-amp variable-speed jigsaw features a front LED, support for 45-degree bevel cuts and six different blades in the box. It normally sells for $50 and has never before been discounted on Amazon.

TACKLIFE JIGSAW FOR $39The Vava immersion blender: $18 with code TUIGN4BR. During my recent Italy vacation, I learned to make gelato — and it starts with an immersion blender. Like this one, which normally runs $28. It includes several handy extras and has a 4.3-star average rating. Cantelope gelato, here I come! (Don’t knock it till you’ve tried it.)
